Follow-up on the problem at the beginning of this thread:
--Called S&W on Monday, Aug 2.
--Received a shipping label on Thursday, Aug 5.
--Shipped it out the same day (Aug 5).
--Received it back on Wednesday, Aug 25.
The enclosed letter from S&W was blank: a header, a footer, and nothing in between. Called S&W, and the Customer Service Rep had no details about the repair in his computer.
The firing pin shaft clearly was replaced, and the safety activation lever was replaced. Not sure what else might have been done, but the trigger feels a bit lighter than it was previously. Maybe I'm imagining that.
The right-side laser button (very difficult to activiate) was not repaired. In fact, it was worse. I have since swapped the right and left laser buttons, and done a little fiddling with the right button to get it to work properly. The left button now is difficult to activiate because it has the "bad" right button. I think that rubber button itself is out of spec, as the center post inside the button clearly is too short to be of much use. I will call S&W again today to request some extra buttons.
I haven't yet had the opportunity to go to the range to shoot the pistol. I've had it for a month, but most of that time was spent with it in repair. I'm a bit concerned about the take-down pin retention problem that many have described. I'll provide an update once I've been to the range.
